Congratulations on your first game jam. I have to say that the game is impressive. It’s really fun and original. I know how it is to get excited in the beginning and loosing motivation towards the end, but you finished it, and it looks and plays great! It’s difficult to play with a mouse, so I think it would be great to add support to use “A” and “D” and/or “left arrow” and “right arrow”. Then it would be easier to time the jumps. I didn’t get further than level 4 because of the controls on PC. I think it would be easier on mobile.
I also like the tutorial levels, it helps me understand the game mechanic. Some puzzles are difficult, but the hints help. Good job on the game!
